You need a Wireless Adapter Card. The wireless card plugs into any Available, unused PCI slot. (PCI slots are White in color. They are located inside the computer on the motherboard)

The Dell Optiplex GX260 has Three PCI expansion slots. (And One AGP expansion slot. The AGP slot is longer in length, than the PCI slot's are. It is also not White in color)

This is Dell Support, and the page for the Dell Optiplex GX260 Service Manual,

http://support.dell.com/support/edocs/systems/opgx260/en/sm/index.htm

Here you can click on Computer Cover to see how to open the computer case. You can also view the motherboard to see the location of the PCI slots, that I have made reference to.
(System Board = Motherboard.
Numbers 1, 3, and 4 that are circled, are PCI slots. Number 2 that is circled is an AGP slot. This is where a graphics card plugs in)

You may have the Small Form Factor, Small Desktop, or Small Mini-Tower Computer. This Service Manual will help guide you with hardware identification, no matter which version of Optiplex GX260 you have.

This, is information about an average low profile Wireless Adapter Card. It is not as reference to advertise this website, nor the card's manufacturer,

    Your desktop computer needs a Wireless Adapter in order to use a wireless router. Your desktop computer does not have one built-in like the laptop does. You have to purchase a wireless adapter.

    I also second what hohox5 stated. (Good solution hohox5!)
    A USB style of wireless adapter may be the way to go. It would be best however, if your HP desktop has the USB 2.0 version, and not USB 1.1
    Since you stated the HP desktop is an older computer, it may have USB 1.1

DOESN'T DETECT WIFI


The wireless feature on a Gateway computer allows you to connect to a network without the hassle of cables. This allows you to browse the Internet conveniently wherever you are. Gateway computers rely on Windows operating systems, which come with a built-in feature to manage your wireless connection. This feature makes turning off your wireless connection an easy process if, for a moment, you prefer to connect to the Internet using a wired connection.

Click the Windows "Start" menu and click the "Control Panel." Click Network and Internet Connections > Network Connection, if you are using a Windows XP Gateway computer. You should see your wireless connection. For Windows Vista and 7 Gateway computers, click "Network and Sharing Center" from the Control Panel and click "Manage Wireless Connections." You should see your wireless connection. Right-click your wireless connection and click "Disable" to turn it off. Close "Network Connections" when you are done.

I think i hve the router hooked up wrong how do i fix it


Connecting Multiple Computers
thru a router to internet






Tips on choosing the right network can be found at http://www.microsoft.com/windowsxp/using/networking/setup/install.mspx





Since you said there are other computer in the house I assume they will all
go thru the router. I also assume you are using ethernet to connect the new
computer so it will be a "wired" connection. A rounter can also have wireless
connections if the other computers have wireless internet on the other
computers.



To connect more than one computer to the Internet, you need a router.
A router allows you to connect several computers to each other and to the
Internet. The router sits between your computers and the modem provided by your
ISP. You connect the router to the modem, and then connect all your computers to
the router.



68573-router-diagram.gif



To connect a router and multiple computers to the
Internet


Contact an Internet service provider (ISP) and have them configure
an Internet connection to your home. If possible, have the ISP place the modem
in the room with your primary computer.



Connect your router to your modem in one of the two following
ways:

If you currently have a computer connected directly to your
modem:
Unplug the network cable from the back of your computer, and
plug it into the port labeled Internet, WAN,
or WLAN on the back of your router.



If you don't currently have your computer connected to the
Internet:
Plug one end of a network cable (included with your router)
into your modem, and the other end of the network cable into the
Internet, WAN, or WLAN port
on your router.

68573-connect-modem-to-router-small.jpg



Plug in your router. After a minute or two, the Internet, WAN, or WLAN light
on your router should light up, indicating that it has successfully connected to
your modem.

68573-internet-port-small.jpg


Determine whether your computer has a network adapter, and add one if
necessary. Instructions to determine if you have a network adaptor or to install
a Network adaptor can be found at http://www.microsoft.com/windowsxp/using/networking/setup/netadapter.mspx



Shut down your computer by clicking Start and then clicking
Turn Off Computer. Then click Turn Off.



Connect the network cable to your computer's network adapter.



68573-connect-computer-small.jpg


Connect the other end of the network cable to your network equipment.



68573-connect-to-router-small.jpg


Start your computer and log on to Windows. Windows automatically detects that
you are connected to the Internet.

Repeat steps 6, 7, and 8 for each one of your computers. If you have a
computer in a different room you can find instructions at http://www.microsoft.com/windowsxp/using/networking/setup/wired.m

How Can One Cable Modem Work With Two Wireless Routers? By Terry Stockdale Leave a Comment In How to Fry a Wireless Router or Two, I wrote about my brother's experience frying a pair of wireless modems in a lightning storm. Last week, I talked about what had happened, why it happened, and what he could do to prevent the problem in the future (this was the third set of routers, plus he lost a computer motherboard in that storm).
This week, we'll look at his network layout, and why he could not get the network to set up properly.
To summarize the situation, he has an office an a shop, with computers on his network in both locations. Some connect via wired connections (Ethernet), while others use wireless connections. His Internet cable comes into the office first.
In the past, he first used Linksys wireless routers. Then DLinks. This time, he chose Belkin wireless routers.
The incoming cable (standard cable-company RG6 coaxial cable) connects to the cable modem.
Then, the cable modem connects to the WAN (wide area network "Internet") connection on the router.
The local wired ports on the router provide connections for two wired computers. Notebooks connect via wireless connections. Finally, one wired connection on the router is used to connect an Ethernet cable that runs 250 feed to the office from the shop.
That cable was the lightning problem, as it runs outside in a conduit just a little bit underground. Effectively, he's got a 250 foot antenna looking for the electromagnetic pulse from a lightning strike. Most of us don't worry about that because our equipment is so well grounded in the house, plus the Ethernet cables we use are much shorter lines. Even if we have underground cable company lines running from their switch boxes to our houses, those lines are usually only exposed about 40 to 50 feet before they enter the dwellings.
Back to the situation. When he hooked up his replacement routers, the router at the shop immediately worked. Not so, on the router in the office. The Ethernet light and the Activity light just poounded away, blinking and blinking rapidly. But, nothing connecting to the router could get to the Internet.
If they connected a computer directly to the Ethernet cable in the office, without running it into the router first, it worked just fine. But, with the router in place, it didn't work.
The problem was the way he connected the two routers. The problem is that there is no Out Of The Box connection that will work reliably. At least one thing, usually two, has/have to be tweaked one way or another.
As one might guess, the easiest way to connect would be to connect one router's WAN connector to the cable modem, using Ethernet cable, and then use Ethernet cable to connect one of the Local Area Network (LAN) connectors on that router ot the WAN router on the other computer.
There is a problem with this setup, but it's easily solved. First, if you're using identical wireless routers, as he was, the wireless routers are both trying to use the same IP Address range and subnet mask for their local area networks.
That works fine for the first router, which is connected to cable modem. On the cable modem side, it gets an IP address on the Internet Service Provider's network - often an actual Internet address and not just a private network address. On the local area network, it assigns the IP address range specified in its setup menu. This often varies by manufacturer. In the case of Linksys, this is 192.168.1.x. In the case of the Belkin routers he bought, it was 192.168.2.x.
The problem occurs at the second router. On it's WAN side, it sees a 192.168.2.x network - but it's default setting tells it to give 192.168.2.x addresses on it's local area network side, too. In other words - it's confused. It doesn't know where to find the Internet because both networks are assigned the same addresses.
The solution was to disconnect the second router's WAN/Internet cable, connect to it via a wired computer, and tell the second router to use a different IP address range. We chose 192.168.3.x.
We hooked up the Ethernet cable to the Internet/WAN side of the router again. The router started working fine, normal light blinks for activity, no more confusion. The computers could get to the Internet just fine.
Problem solved.
That solved the Internet connection problem. However, no computers in the office would be able to share files or printers with the shop, nor would computers in the shop be able to share with the office. That was both acceptable and intended, in this case.
It could be done; however, that would require a different configuration on the routers and connections.

I need to connect a D-Link router to my cable modem so that I can use my laptop anywhere in my home


Cable-modem <-- Ethernet cable --> WAN (or "Internet") port on the router

LAN port on router <-- Ethernet cable --> network-port on your laptop

Then, access the "built-in" web-server on the router,
and run the "Wireless Networking Setup" wizard:
* to set an SSID ("network-name")
* an encryption-level (Hint: choose 'wpa')
* a password for your wireless network

Then, disconnect the Ethernet cable from your computer,
and then "wireless available wireless networks".
Select your newly-created network, and connect to it.

Can not connect to my wireless router


1. Choose your wireless equipment The first step is to make sure that you have the equipment you need. As you're looking for products in stores or on the Internet, you might notice that you can choose equipment that supports three different wireless networking technologies: 802.11a, 802.11b, and 802.11g. We recommend 802.11g, because it offers excellent performance and is compatible with almost everything.
Shopping list
  • Broadband Internet connection
  • Wireless router
  • A computer with built-in wireless networking support or a wireless network adapter
A wireless router
The router converts the signals coming across your Internet connection into a wireless broadcast, sort of like a cordless phone base station. Be sure to get a wireless router, and not a wireless access point.
A wireless network adapter
Network adapters wirelessly connect your computer to your wireless router. If you have a newer computer you may already have wireless capabilities built in. If this is the case, then you will not need a wireless network adapter. If you need to purchase an adapter for a desktop computer, buy a USB wireless network adapter. If you have a laptop, buy a PC card-based network adapter. Make sure that you have one adapter for every computer on your network.
Note: To make setup easy, choose a network adapter made by the same vendor that made your wireless router. For example, if you find a good price on a Linksys router, choose a Linksys network adapter to go with it. To make shopping even easier, buy a bundle, such as those available from D-Link, Netgear, Linksys, Microsoft, and Buffalo. If you have a desktop computer, make sure that you have an available USB port to plug the wireless network adapter into. If you don't have any open USB ports, buy a hub to add additional ports.
2. Connect your wireless router Since you'll be temporarily disconnected from the Internet, print these instructions before you go any further.
First, locate your cable modem or DSL modem and unplug it to turn it off.
Next, connect your wireless router to your modem. Your modem should stay connected directly to the Internet. Later, after you've hooked everything up, your computer will wirelessly connect to your router, and the router will send communications through your modem to the Internet.

  • If you currently have your computer connected directly to your modem: Unplug the network cable from the back of your computer, and plug it into the port labeled Internet, WAN, or WLAN on the back of your router.
  • If you do not currently have a computer connected to the Internet: Plug one end of a network cable (included with your router) into your modem, and plug the other end of the network cable into the Internet, WAN, or WLAN port on your wireless router.
  • If you currently have your computer connected to a router: Unplug the network cable connected to the Internet, WAN, or WLAN port from your current router, and plug this end of the cable into the Internet, WAN, or WLAN port on your wireless router. Then, unplug any other network cables, and plug them into the available ports on your wireless router. You no longer need your original router, because your new wireless router replaces it.
  • 3. Configure your wireless router
  • Using the network cable that came with your wireless router, you should temporarily connect your computer to one of the open network ports on your wireless router (any port that isn't labeled Internet, WAN, or WLAN). If you need to, turn your computer on. It should automatically connect to your router.
    Next, open Internet Explorer and type in the address to configure your router.
    You might be prompted for a password. The address and password you use will vary depending on what type of router you have, so refer to the instructions included with your router.
    As a quick reference, this table shows the default addresses, usernames, and passwords for some common router manufacturers.

    Internet Explorer will show your router's configuration page. Most of the default settings should be fine, but you should configure three things:
    1. Your wireless network name, known as the SSID. This name identifies your network. You should choose something unique that none of your neighbors will be using.
    2. Wireless encryption (WEP) or Wi-Fi Protected Access (WPA), which help protect your wireless network. For most routers, you will provide a passphrase that your router uses to generate several keys. Make sure your passphrase is unique and long (you don't need to memorize it).
    3. Your administrative password, which controls your wireless network. Just like any other password, it should not be a word that you can find in the dictionary, and it should be a combination of letters, numbers, and symbols. Be sure you can remember this password, because you'll need it if you ever have to change your router's settings.
    The exact steps you follow to configure these settings will vary depending on the type of router you have. After each configuration setting, be sure to click Save Settings, Apply, or OK to save your changes.
    Now, you should disconnect the network cable from your computer.
    4. Connect your computers to the wireless network If your computer does not have wireless network support built in, plug your network adapter into your USB port, and place the antenna on top of your computer (in the case of a desktop computer), or insert the network adapter into an empty PC card slot (in the case of a laptop). Windows will automatically detect the new adapter, and may prompt you to insert the CD that came with your adapter. The on-screen instructions will guide you through the configuration process.

When i hook it up i get the laptop to pick up the signal but the desktop will not go online


on the hind side of the modem how many ports do you see
my guess one port slightly seperated and named INTERNET or WAN and four more ports numbered 1,2,3,4

now connect the network cable from the modem to the WAN / INTERNET port and connect the laptopand PC to the ports1,2

now check to see if there is connection to only on Laptop or both

but if you have conection to only the laptop/PC connected to port1 then try this small trick

move the laptop to port 3 and in port 1 connect the cable from the modem which was connected to the WAN / INTERNET port

No internet connection on two desktops


Hi Tony, you think your laptop is connecting to your neighbor's wireless network. So try this.
1:Go to Control Panel, click on network and internet connections, double click NETWORK CONNECTIONS. Point your mouse to the WIRELESS NETWORK CONNECTIONS. It should show that you are connected(and it will show the name of the network that you are connected to). If you do not recognize the name of the network that you are connected to then you are connected to your neighbor's network.

IF YOU ARE CONNECTED TO linksys--unsecured wireless network, there is a chance that your wireless router is not functioning at the moment.

Try this first and i will be waiting if you have a follow up problem.


Good Luck
